Abstract in another language

The intention of this work is to investigate a contactless in situ microwave-based technique to detect coke deposits in an industrial fixed-bed catalyst. The steel reactor is thereby used as an electrical cavity resonator. The perturbation in the resonator is measured in the microwave range by a vector network analyzer and two waveguide feeds (coaxial antennas). Due to coke loading, the electrical conductivity of the catalyst pellets increases strongly. This leads to changes in the resonance behavior that are mirrored by the scattering parameters. Therefore, the locally homogeneously distributed coking process and the coke burn-off process that starts at the front of the reactor and moves through the fixed bed can be observed by the microwave-based method.
